What does oxygen do for fire?
Fire is the release of heat and light during the very rapid combination of oxygen with another substance that we call the fuel of the fire. Although there are other oxidizers that can perform a similar function, in most cases in everyday life you cannot have a fire without a source of oxygen.
What type of energy does a fire use?
Chemical potential energy. Fire is a chemical reaction caused by heat Fuel and oxygen (usually) The fuel is combusted exothermically (ie giving off heat) with oxygen which is a chemical reaction. This causes surrounding fuel to heat up a react exothermically with the oxygen, propagating the fire.
True or false fire will not burn without oxygen?
True, fire must have oxygen to burn.
Why does water usually put out fire?
Water stops oxygen from getting to the flame, and oxygen is the fire's food.
The key elements for a fire?
Fuel, Oxygen and Heat Fuel, Oxygen and Heat Fuel, Oxygen and Heat
What should you do during a fire?
Well a fire is made up of three things, heat, oxygen and fuel. So if there is a fire you need to get rid of one of these three and the fire will go out, this is why we use fire extinguishers because the foam covers the fire stopping oxygen from getting to it.
Do fire extinguishers use oxygen?
No. Fire is a chemical reaction between oxygen and a flammable material. Adding extra oxygen speeds up the reaction, making the fire burn even hotter and making it easier for the fire to spread.
Why do firefighters need oxygen?
At the place of fire, the burning things use up all the oxygen(burning is nothing but reaction with oxygen) and fill the place with Carbon Monoxide and dense fumes, so to be able to stand there and douse the fire, firefighters do need Oxygen to breathe properly.
How does fire affect air?
Part of air is made up of oxygen without which fire can't happen. Air can feed a fire; it contains oxygen.
Why fire is pointing up?
to reach the oxygen for fuel
Why do fire men use sand to put a fire out?
because it takes away the oxygen which fuels a fire.
Why would you use foam to put out a fire?
Not normal foam but carbon dioxide foam from a fire extinguisher. This special foam covers the fire and takes all the oxygen out of it, and with no oxygen, no fire!!!
What is one use for oxygen?
Oxygen is used by people as we breath it out.one of the uses of oxygen is that fire needs it to burn
Why do you use foam to put out a fire?
The foam cuts the connection of fire with air (oxygen) & thus puts out fire.
What happens you remove fuel and oxygen from fire?
When you remove fuel and oxygen from a fire, the fire will be extinguished. Fire requires fuel (such as wood or gas) and oxygen to continue burning, so removing either one will stop the combustion process.
Why is oxygen used up when a fire burns?
During a fire, oxygen is used up because it is a key element in the combustion process. The fire's heat breaks apart the oxygen molecules, allowing them to combine with other substances in the fuel, releasing energy in the form of heat and light. This rapid oxidation process is what sustains the fire and consumes the available oxygen in the process.
Why do you use foam on a oil fire?
foam is used for fire suppression. what it does is it cools the fire and to coats the fuel, preventing its contact with oxygen, and then the fire is out.
